FIRE-ESCAPE.

Specification of Letters Patent.

Patented Nov. 12, 1907.

To all'whom it may concern: l

Be it known that we, RICHARD SCHAPLER, a subject of the German Emperor, residing at ll Burgstrasse, Frankfort-on-the-Main, in the Empire of Germany, and CARL WASSER, a subject of the German Emperor, residing at l0 Rudolfstrasse, Nremberg, in the Empire of Germany, have invented certain new and useful lmprovements in and Relating to Fire-Escapes and the Like, of which the following is a specification.

This invention relates to telescopic fire-escapes.

The fire-escapes hitherto known have the disadvantage that considerable time is wasted in drawing out the single telescopic tubes of the escape one by one, and such escapes have, with others, the general disadvantage` that a telescoping of the ladders is impossible except when the escape is nearly perpendicular, inasmuch as the telescoping is only effected under the weight of the several parts. These disadvantages are avoided according to the pres-ent invention, which is hereinafter described and illustrated in the accompanying drawings.

Figure l is a general view on a small scale of a reescape provided according to the invention. Figs. 2 and 3 show transverse longitudinal sectional views on an enlarged scale. Figs. 4 and 5 are detail views, and Fig. 6 illustrates in part longitudinal section a modified construction.

In carrying the invention into effect in its application to a lire-escape as illustrated in the accompanying drawings, a carriage a is provided, upon which a support b is mounted. The telescoping tubes d/ to d4 are .the drawing out is effected by means of fluid under pressure provided in' iron receptacles, which fluid' under pressure, in the first instance, forces the inner tube outward, whereupon the other tubes follow in succession. On the other hand in the arrangement provided according to the present invention the pressure affects only one tube d2 (Fig. 2). This tube is connected to the piston 1 which moves in the cylindrical tube d/, and it carries within it the tube d3 which is connected to the piston 2.` The tube d3 carries within it the tube d4 which is connected to the piston 3. The piston l carries within a recess suitably provided for it a pulley s around which passes a chain cord, or other flexible member t connecting the piston 2 with the top of the tube d. Similarly the piston 2 is provided with a pulley 21 around which passes a chain cord or other ilexible member u which connects the piston 3 with the top ofthe tube d2.

The piston 2 is connected to the top of the tube d by a chain cord or other flexible member o e passing through a curved hole 22 formed in the piston 2 and passing over pulleys o a mounted upon the iop of the tube d2, the two ends of the flexible member o f being connected lo the top of the tube CV. Similarly the piston 3 is connected to the top of the tube P by means of a flexible member h y passing through a curved hole 3l formed in the piston 3, and over pulleys 71, g provided upon the 10p of the tube d, lt will then be understood that when the piston Il. and the tube d2 is forced upwardly upon the admission of fluid under pressure into the tube tl/ by reason of the ends of the flexible member o e which passes round the piston 2 being connected to the top of the tube df, the piston 2 and the tube d3 will also move upwardly, and similarly by reason of this upward movement ofthe tube d, the piston 3 and tube d* will also move upwardly until each tube is extended upwardly to the utmost limit of its length.

To the top of the casing d is attached the rope t which, passing over the pulley S fastened to the piston l, is secured to the bottom of the piston 2, consequently on the downward movement of the piston l, the portion of the rope t between the pulley S and the piston 2 becomes shortened and the section l3 is drawn into the section J2. In a like manner the tube d* is simultaneously drawn within the tube d3 by a similar arrangement of the rope u and pulley 2l. The slidable section 1/ i12 v3 are attached respectively to the sliding piston tubes CF d3 d* and the bottom section o to the fixed tube d.

On its outer periphery the tube d2 (Figs. 2 to 5) is u provided with inclined teeth or threads of great pitch, and gears with a set of gear wheels f which is operated by a downwardly directed spindle fi, which is rotated by hand or motive power. According to the direction in which the spindle i is rotated to the right or the left, the tube d2 rises or lowers, and the same movement, which however is increased in extent, is imparted to the tubes d2 and d4. By the arrangement of the hand wheel k upon the spindle t' it is possible to regulate the movement of the telescopic tubes either on rising or descending, even where these movements are not effected on the operation ofthe wheel lc itself.

In Fig. 6 a modified construction is illustrated, ill which the screw threaded tube d2 is dispensed with, and replaced by a special spindle l carried within the casing, and which passes through the base m of the first movable tube d", wnich latter is provided with a female screw thread, so that the operation will be substantially the same as in the first modification.

What we lclaim as our invention and desire to secure by Letters Patent is.-

In [irc escapes or masts, a fixed supporting member, a sliding member, means for causing the movement of said sliding member, a second sliding member capable of movement with reference to the first sliding member ilexible means for connecting the upper extremity of the fixed supporting member with the lower extremity of the second sliding member after rst passing around the lower extremity of the iirst sliding member, and exible means for the connection of the lower extremity of the second sliding member with the upper extremity of the xed supporting member after first passing over the upper extremity of the first sliding member.

2. ln fire escapes or masts, a xed supporting tube, a sliding tube'within said fixed tube, and a second sliding tube within said first sliding tube, a exible member con necting the top of the fixed tube with the bottom of the Second sliding tube after first passing around the bottom of the rst sliding tube and a flexible member connectingvthe lower end of the second sliding tube with the top of the fixed tube after -first passing over the top of the first sliding tube substantially as described.

Il, In fire escapes or masts, a fixed supporting tube, -a sliding, tube within said fixed tube, and a second sliding tube within said first sliding tube, a iiexiblc member connecting the top ot the fixed tube with the bottom of the second sliding tube after first passing around the bottom .ot' the first sliding, tube and duplicate flexible members one passing on each side of the second sliding tube and connecting the lower end `of the second sliding tube with the top-of the xed tube after first passing over the top of the lirst slidingtube substantially as described.

4. In`re escapes or masts members constituted of a number of parts capable of sliding within each other, iexible means for connecting theupper extremities of the one of said parts with the lower extremities of the adjacent part said flexible means passing around the lower extremity of an intermediate part, and iiexible means for connecting the top of one part to the bottom of an adjacent part, said exible means passing o ver the top of an inter mediate part, mechanism for regulating the extension or contraction of said members substantially as described.

ln testimony whereof we have signed oui` namesrto this specification in the presence of two subscribingwitnesses.
